(743+746+3)/20 = 75
Would be the average number of round trip trades (buy then sell, sell short then buy to cover) per year.
If you pay $10 per trade, $20 per round trip, then $1500 per year in commissions.
Not a system for everyone.
Now if we could prove the returns did not significantly waver using 2X Rydex funds traded AM, then it would be cheap and easy to use. I believe it would still perform well averaged out over the years, but can't prove it.
